HERMAN HOLLERITH, OF GARRETT PARK, MARYLAND, ASSIGNOR TO THE TABULATING MACHINE COMPANY, A CORPORATION OF NEW JERSEY.

REGISTERING APPARATUS.

Specification of Letters Patent.

Patented June 25, 11912.

Application filed August 26, 1905. Serial No. 275,897.

To all whom it may concern:

Be it known that I, HERMAN HOLLERITH, a citizen of the United States, and a resident of Garrett Park, Montgomery county, Maryland, have invented certain new and useful Improvements in Registering A paratus, of which the following is a full, 0 ear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to the general class of registers and comprises apparatus by which items may be counted or totalized and, when desired, recorded on a printed record.

I have illustrated in the drawings and will describe in detail a specific and preferred form of apparatus embodying my invention which is not, except as indicated in the claims, restricted to the specific features illustrated or described, since the apparatus is susceptible of modifications in which the beneficial results of my invention would be realized to a greater or less degree and which would not involve any departure from the scope of my invention.

The particular embodiment of my inven-- tion illustrated in the drawings comprises ten separate counters or registers grouped together side by side. Each counter is arranged to count or add units, one by one, and contains four members, one for units, one for tens, one for hundreds and one for thousands from which the positions of the indicators are determined and which I therefore refer to as positioning members. These positioning members, which are all counterparts of each other, may be grouped together, as the character of the work may require. A printed record of the results obtained by the operation of the apparatus may be made at any stage of the operation if desired, and in order that this record, which is made in reversed position, shall read properly from left to right, the positioning members, of which any desired number may be employed, are as shown arranged in reverse order with the units memher at the left, viewed from the front or printing end of the machine.

As the particular form of apparatus shown is intended to count units, one at a time, the units member only is actuated by the power or driving mechanism, in this instance consisting of an electro-magnct, the other members being actuated only by the transfer or carrying mechanism. employment of these positioning members I am enabled to dispense entirely with the adding or number wheels or members heretofore constituting an essential element of adding mechanisms, thereby saving the space required for them and securing an extremely compact construction.

In the drawings Figure l is a plan View partly in section of one form of apparatus, embodying my invention; Fig. 2 is a sectional elevation on the line 22 (Fig. 1); Fig. 3 is a similar view showing the parts in a different position; Fig. 4 is a detail on an enlarged scale showing a plan of the positioning members of one counter; Fig. 5 is a sectional elevation showing a modification of the construction illustrated in Figs. 1 t; Fig. 6 is a front elevation of one of the positioning members; Fig. 7 is a side elevation of one of the units positioning members; Fig. 8 is a similar view of one of said members of higher order; Fig. 9 is a detail showing part of the resetting mechanism and Fig. 10 is a diagram showing an operative arrangement of circuit devices by which the mechanism may be actuated.

Similar reference characters are employed to designate like parts in all the views.

The apparatus as illustrated is supported in a case or frame 1, in which is journaled an arbor 2 which extends entirely across the frame and supports the positioning members of all the counters. The positioning members of each counter are designated generally by the letter A, and specifically 3 represents the units, 4 the tens, 5 the hundreds and 6 the thousands member. All of said members are duplicates in construction, and each constitutes a structural unit consisting only of a ratchet wheel 7 and cam 8 integrally formed or otherwise rigidly con nected -so as to rotate together as a single element. It will be observed that each of said members may be formed of thin plates or disks so that, in their side by side relation, they will occupy an exceedingly small compass. This is a very desirable and practical feature in machines of this character where the mechanisms are multiplied to a large extent. As shown the cam 8 is a double cam consisting of 'two like sections dia- By the I ately from its heel to its point.

Each counter is operated by a suitable power or actuating device such as an electro-magnet 10, to the spring retract-ed armature 11 of which is pivoted a pawl 12 which is held in engagement with the teeth of the ratchet wheel 7, on the units positioning member of the counter, by a retractile spring 13, so that each time the magnet 10 is energized and attracts its armature the units member will be advanced the distance represented by one tooth of the ratchet wheel. An abutment 14 engages the end of the pawl '12, guiding it properly against, the ratchet teeth and preventing overthrow. A check pawl 15 engages each ratchet wheel and prevents backward rotation thereof.

Suitable mechanism must be provided to effect the carrying or transfer from each member to that of the next higher order. I have shown one practical form of such apparatus which cooperates properly with the other elements of the apparatus and which comprises carry levers 20 pivoted as at 21 and pressed toward the positioning members by springs 22. A finger 23 is formed on each lever and is arranged to be engaged by the advancing surface of a cam 8. A pawl 24 is pivotally secured to each of the leve'rs 20 in position to engage with the teeth of the ratchet ,7 on the member next higher in order, being held against the ratchet teeth by a spring 25. An abutment 26 serves as a stop to prevent overthro'w by the carry lever and pawl. As the advancing surface of the cam 8 on the member of lower order engages the finger 23, the lever 20 will be forced back, carrying the pawl 24 back to drop behind the next tooth on the ratchet of the member of higher order and when the revolution of the cam 8 carries the point of the cam free of the finger 23 the spring 22 will force the lever and pawl forward thus actuating its ratchet wheel to move its counting member one tooth, it being understood, of course, that this occurs when the member .which actuates the lever moves from a position representing 9, corresponding to the point of one section of the cam, to zero, denoted by the heel of the succeeding section. Means are also provided for resetting the positioning members to zero atthe end of an operation. The mechanism which I have devised for this purpose comprises a lever 30 which is mounted on one end of the arbor 2. A spring-pressed pawl 31 is carried by the lever and engages a notched disk 32 made fast to the arbor, locking the lever to the arbor when the lever is moved forwardly but permitting the lever to be returned to its initial position Without turning the arbor.

The disk 32 is provided with two of said notches in diametrical relation. A collar 33 provided with two diametrically arranged notches 34 is also secured fast to the arbor 2 and a dog 35 carried by a spring-pressed arm 36 is arranged to yieldingly engage one of the notches in the collar 33, when the arbor 2 has been moved to the forward limit of its movement by the lever 30, so as to hold the arbor against movement on the return or backward movement of the lever. The arbor 2 is provided with two diametrically arranged catch notches 37 for each positioning member and each of such members carries a spring-pressed pawl 38 held in a recess 39. in the face of the cam 8. The notches 37 for the units member are in such relative arrangement'to the pawl 38 carried by the member that when the lever 30 is actuated to turn the arbor forward to reset the members, one of the notches 37 for the units member will engage the pawl thereon at some point in the movement of the arbor and carry the units member to zero. The notches 37 on the arbor 2 for the different members may be arranged in axial alinement as by forming continuous grooves on opposite sides of the arbor. In such case the pawl-38 on the units member is placed one tooth in advance of the pawls on all the other members so that while the units memher is reset to zero position by the resetting movement of the arbor 2, the members of higher order will all be carried only to their 9 positions. The resetting movement -of the arbor 2 will turn the collar 33, fast thereon,

throwing the dog 35 out of the notch 34: and swinging'the arm 36 backward against the resetting levers 20 to hold them in a retracted position until the units mem; ber reaches its zero position when the dog 35 will enter the notch on the opposite side of the collar 33 permitting the springs 22 to throw the levers 20 forward to move the members of higher order from their 9 to their zero positions, the transfer mechanism thus completing the resetting movement of these members.

In order to provide for a reading of the results of operation and also to provide for the making of a printed record of' such results if desired, I have devised means by which such a reading or record can be made at any time at the will of the operator. These means comprise a series of indicators 40, one for each positioning member of the machine, indicated generally by the letter B. The indicators 40 may be arranged in various ways. Duringthe operation of the positioning members, they are inactive and disconnected therefrom, thereby relieving the operating mechanism from the work of actuating the indicators. The indicators 40 are of segmental form and are mounted loosely, so as to be independently movable, on an axle 41 extending across the machine and journaled in the sides of the frame 1. Suitable indicating characters 42, preferably in type form, are arranged on the periphery of each segment. In the case of :1 units counting machine these characters would consist of the characters 0 to 9 inclusive, and, in the construction illustrated, with the cipher at the top of the segment. The indicating characters in their spaced relation will correspond with points on the surface of the cam 8 opposite the ratchet teeth of the positioning member.

From the foregoing partial description of the apparatus illustrated it will be apparent that the result of any counting or adding operation will be denoted by effecting a correlative positioning of the members A and indicators B, and that if each of the indicators B be brought into a position corresponding exactly with the position of its positioning member a character on each indicator corresponding to that position will show at an opening 55 in the front of the machine case from which a visual reading, or as will be presently described, a printed record may be made. My invention comprises means for accomplishing this correlative positioning of the members A and B, and in the drawings I have shown such means in a preferred form; but other equivalent means may be employed as my invention does not reside in the precise form or arrangement of the devices illustrated.

The devices which I preferably employ for the purpose just referred to are shown most clearly in Figs. 2 and 5 which show the indicators arranged to be entirely free from engagement or connection with the positioning members, during the operation of the latter, thus relieving the operating magnets from all work in connection with the operation of the indicators and reducing the power required to operate the apparatus to a minimum. Referring now to Figs. 2 and 3, each indicator is provided with a member 43 which is constructed as a complement of the cam or cam section 8 with which it cooperates. In the construction illustrated, this member is shown with an eccentric stop surface 44, which is preferably notched or stepped in regular order corresponding to points on the surface of the cam 8 opposite the teeth of the ratchet wheel 7. Each of the indicators 40 is designed to be normally drawn in a direction for bringing the characters 42 successively into proper position by suitable means, such as a retractile spring 45 made fast at one end to a fixed support, and at its other end connected at 46 to the lower side of the indicator body at one side of its pivotal support. All the indicators 40 are held in inoperative or inactive positions against the tension of their actuating springs 45 by a suitable restraining device such as a universal bar 50 which is carried by yoke arms 51 secured to the indicator axle 41. This axle also has rigidly connected thereto, preferably as an extension of one of the yoke arms 51, a lever 52 conveniently arranged at one side of the frame. The means for securing the correlative positions of the members A and the indicators B also comprise a series of intermediate devices, one for each indicator, which serve to arrest and hold the indicators in their proper positions and which are designated generally by the letter C. These intermediate devices, which I refer to as indicator stops, asshown in Figs. 2 and 5 consist of a lever (30, pivotally supported as at 61 to a fixed support 62. A spring 63 is secured to the upper end of each lever. In Fig. 2 the spring tends to hold the upper end of each lever against a restraining bar 64 which extends across the machine and is pivotally supported at its upper edge as at 65. An arm (36 is secured to the bar 64 and carries a stud 67 which projects through a guide slot 68 in the side of the frame or case 1. The stud 67 is ngaged by a notch 69 in the lever 52, when the lever is in its at rest position, to hold the restraining bar 64 against the levers 60. Each stop lever 60 is provided with a camengaging finger 7 O which, as shown in Fig. 2, is held just clear of its cam 8 when the indicator stops are in the position just described; but when the restraining bar (54 is released by the movement of the lever 52 and releases the levers 60 each of the cam engaging fingers thereon will be drawn against the cam surface of its positioning member by the pull exerted by the springs 63. The movement of the lever 52 which releases the stop indicators also, in its further movement, moves the restraining bar 50 and permits the springs 45 to actuate the indicators, drawing the members 43 thereof upward toward the free end 71 of the levers 60 which have assumed various positions determined by the respective positions of the cams on the positioning members. In their upward movement, therefore, the end 71 of each lever 60 will engage the tooth of its indicator member 43 which corresponds with the point on the surface of its cam 8 with which the finger 70 is engaged, thereby arresting the movement of each indicator in a corresponding position and showing at the opening 55 its corresponding character.

For the purpose of making a printed record of the indicator characters thus displayed or brought into position, I have devised a record making or printing device 'which as illustrated comprises an inking ribbon 80 for each counter, which is wound and unwound on upper and lower ribbon spools 81 and 82. The upper ribbon spools 81 are all secured to a common axle 83 which may be turned to wind the ribbon in one direction by a finger piece 84. The lower ribbon spools 82 are similarly mounted and actuated. The paper or sheet 85 upon which the record is to be made may be conveniently supported and guided by a paper guide 86. A paper feeding roll 87 is mounted on an axle ournaled in the frame of the machine and cooperates with the stud rollers 88 to properly feed the paper. The feeding roll 87 may be suitably actuated by a finger piece 89 secured to its aXle. The printing mechanism also comprises an impression roller 90 journaled in a horizontal position in a block 91 arranged to slide in suitable guides 92 across the front of the machine. The journal support of the impression roller is provided with a hand piece 93 by means of which the roller may be reciprocated from either side of the machine across the face of all the indicators thereby impressing upon the paper all the characters on the indicators which are in printing position. A yielding pressure of the impression roller 90 against the printing characters'may be provided for, as for instance by forming the periphery of the impression roller of some suit-able resilient material.

In Fig. 5 I have shown a modification of the apparatus embodying my invention in which. the carry levers 20 and the restraining devices for the indicator stops are entirely dispensed with, carry pawls 241 being pivoted on and actuated by levers 60 and cam engaging fingers 70 being held in constant engagement with cams 8 by retractile springs 63, so that when the indicators are released the ends. 71 of the stop levers will engage the proper tooth of the indicator members 13* and arrest each indicator in a position corresponding to the position of its positioning member. This modification simplifies the const-rrction of the apparatus by reducing the number of parts.

My invention is particularly adapted for all classes or character of work where a large number of closely grouped easily read counters are required. It is, for instance,

particularly adapted for use in the Hollerith tabulating system and in Fig. l I have indicated diagrammatically a method of its employment in such systems of which one of the distinguishing characteristics is a record card 100 upon which the data to be counted or registered is denoted by the location of index-points preferably formed by punching the record cards at the proper indeX-point positions. Suitable circuit closing devices, such as mercury cups 101 and spring pressed pins 102, are controlled by the record' card to close an electric circuit through the punched holes thereof. Each of the actuating electro-magnets 10 is connected with one of the mercury cups so that when the pins 102 are advanced those pins which are opposite perforations on the card will enter their mercury cups and close a circuit through their respective magnets. My invention may also be advantageously employed in telephone exchanges and in fact in any work of similar character where it is essential that a large number of separate counters should be assembled so as to be readily observed and manipulated by a single operator.

Having thus shown and described my invention, what I claim as new and desire to secure by Letters Patent is:
